A White House petition requesting that dentist Walter Palmer, who killed a prized lion in Zimbabwe, be extradited to the African nation to face justice should receive a response from the Obama administration.

The Empire State Building's famous light displays were used to draw attention endangered wildlife. Along with Cecil, whose death has sparked international outrage, a snow leopard, tigers, lemurs and various snakes, birds and sea creatures were projected onto the building.

The spectacle was staged to promote the documentary "Racing Extinction," a production of the Oceanic Preservation Society. Cecil wasn't included in the presentation originally but was added to honor him after he was killed, an Oceanic Preservation Society spokesperson said.

With the help of 40 projectors, images of the endangered wildlife moved across the south side of the building, dazzling viewers on the street and in nearby buildings. The moving images were a first for the Empire State Building, which is normally lit with colors and the occasional light show.

South Bronx cases double to 65 since Thursday

1977: Scientists at the Centers for Disease Control announce that they had sufficient laboratory evidence to implicate a previously unknown strain of bacteria as the cause of Legionnaire's Disease, now named Legionella pneumophila. An outbreak of the potentially fatal infectious disease in Philadelphia in 1976, largely among people attending a state convention of the American Legion, led to the name "Legionnaires' Disease." After the bacteria causing the illness was named, the name of the illness was changed to legionellosis.

The number of deaths in the New York City Legionnaires' disease outbreak is up to four.

Seventy-one cases of the flu-like disease have been reported since mid-July in the South Bronx, up from 31 on Thursday, the city Department of Health and Mental Hygiene said Sunday.

Legionnaires' disease is a respiratory bacterial infection usually spread through mist that comes from a water source, such as cooling towers, air conditioning or showers. It is not transmitted person to person. Symptoms of the disease include fever, chills and a cough.

Most people recover, but between 5% to 30% of those who get the disease die, according to the U.S. Centers for Disease Control and Prevention.

The four victims were all older adults with additional underlying medical problems, the city said. Fifty-five individuals are hospitalized.

"We are conducting a swift investigation to determine the source of the outbreak and prevent future cases. I urge anyone with symptoms to seek medical attention right away," Dr. Mary Bassett, commissioner of the health department, said on Thursday.

The department's probe includes testing water from potential sources in the area.

Five buildings in the outbreak cluster, including a hospital and a hotel, have so far tested positive for traces of the legionella bacteria. Environmental cleaning and taking any corrective measures needed has been completed in all five locations, the city said Sunday.

"The New York City water supply does not pose a risk, so people should continue to feel confident in drinking tap water to stay cool during this period of hot weather," said Bassett.

At a City Hall press conference Thursday afternoon, Mayor Bill de Blasio warned that anyone with symptoms should get tested, but he said that most New Yorkers are not at risk.

The city health department continues to employ disease detectives to investigate the source of the outbreak and is conducting outreach to vulnerable populations including the elderly and homeless. A town hall discussion between community members and city medical experts entitled "The Facts About Legionnaires Disease" is scheduled for Monday evening.

Bronx Borough President Ruben Diaz Jr. said on Friday that his office will push for legislation to create a citywide inspection system that would test building water infrastructure for the disease and others.

"The city must create a new inspection system for these systems, just as we inspect other critical systems such as elevators," Diaz said in statement.

An outbreak of the disease killed two people at a hotel in downtown Chicago in 2012.

An estimated 8,000 to 18,000 hospitalized cases of Legionaires' disease occurs each year in the United States. An outbreak of the disease in Philadelphia in 1976, largely among people attending a convention of the American Legion, led to its name.

A dozen years in the NFL, most of them as the perpetually smiling blue-collared soul of the Pittsburgh Steelers, left him spent. The Steelers had just watched a 15-1 season evaporate a win shy of the Super Bowl. The tread on the force of nature simply known as "The Bus" had grown awfully thin.

All those carries. All those yards - many of them with a host of defenders along for the ride - had sapped his will. He privately told teammates he was set to retire, leading wide receiver Hines Ward to openly weep about the inability to get a championship ring for the player who served as the de facto big brother in the locker room.

Then Ben Roethlisberger called. So did coach Bill Cowher, who outlined a scenario where Bettis could serve as the "finisher" while young Willie Parker did the bulk of the work. Each plea came with a variation on the same thing: The Steelers could take that elusive step to a title if Bettis came along for one last ride.

"At the 12th hour I was convinced to come back and give it one more shot," Bettis said. "Boy, I'm glad I did."

The decision changed the arc of the franchise, and most likely Bettis' spot in history. With Bettis as the emotional touchstone, the Steelers rode a wave of momentum that crested in Detroit. Playing a few miles from his childhood home, Bettis walked off Ford Field in a sea of confetti with the Vince Lombardi Trophy aloft after Pittsburgh smothered Seattle for its first Super Bowl victory in a quarter century.

The triumph gave Bettis the storybook finish his teammates promised.

"I would have been one of those guys, 'I was really good but,'" Bettis said. "I would always have that 'but' there. 'He was a great player but they never won championship.' ... It takes that "but" away and all you focus on is the fact that hey, he was a great player."

Perhaps the final one of his kind. When Bettis is inducted into the Pro Football Hall of Fame on Saturday, he'll do it as the sixth-leading rusher in NFL history (13,662 yards) and maybe the last who gained most of them by having his body double as a cannonball.

The 5-foot-11, 252-pound Bettis played up the "Fat back" persona, even if there wasn't always truth in advertising. Sure, he loved to dip his shoulder or mash a massive thigh into a defender. Give him a little room though, and the feet that Bettis once believed would make him a professional bowler were only too happy to run away from you.

"He could make cuts you didn't think a big guy could make," said Steelers president Art Rooney II.

Bettis always made a habit of zigging when zagging would have been easier. Bettis admitted to briefly selling drugs while growing up in Detroit, only to end up on scholarship at Notre Dame. Coach Lou Holtz turned him into a fullback with a rare combination of speed and power. The Los Angeles Rams selected Bettis with the 10th overall draft pick in 1993, and he responded by winning Rookie of the Year, rushing for 1,429 yards as the lone threat on a team that won five games.

After the franchise moved to St. Louis, Bettis clashed with new Rams coach Rich Brooks, who invited Bettis to search for a new home after the 1995 season. Pittsburgh, coming off a Super Bowl loss to Dallas and looking for stability in the backfield, couldn't get to the phone fast enough.

"It was one of those things that you couldn't believe we had the opportunity when he became available," Rooney said. "Everything just sort of fell into place."

Second and fourth-round picks in 1996 brought Bettis and a third-round pick, one of the more lopsided trades this side of Herschel Walker. Bettis soon provided a reminder of what St. Louis said it could do without, with 129 yards and two scores in a 42-6 destruction of his old team.

"He ran all over them," Rooney said. "That day was the fastest I ever saw him run.

"Afterwards some of the guys in Rams' management were shaking their heads and we were laughing, not at them really, but laughing."

The party continued for a decade, Bettis the steadying presence while taking handoffs from Mike Tomczak, Kordell Stewart, Tommy Maddox and Roethlisberger. All those yards, however, dried up in the postseason. When Pittsburgh fell to New England in the 2004 AFC championship game, Bettis thought his last chance to go out a winner was gone.

Roethlisberger spearheaded the recruiting effort to entice Bettis back, even in a reduced role. In a position most stars chafe at late in their career, Bettis thrived.

And when required, the Bus could still hit the gas. Trying to get back in the playoff hunt, Pittsburgh hosted Chicago in December 2005. Bettis rumbled to 101 yards and two touchdowns in the snow, including a 5-yard score in which Bettis ran through star linebacker Brian Urlacher for the final 6 feet.

It was vintage Bettis at a time a teetering season desperately needed it.
